If there is a chance, why not?”In terms of the war, Bahrain remains a military target in the conflict, but Saudi Arabia has avoided being dragged into the fighting again, meaning it could be the ideal race to put back on the calendar.Either way, Domenicali has said that F1 has until the summer break to decide whether it can add another race to the calendar.“I think that the gap to do the eventual possibility of doing one of the races that we have not done, we need to do it before the summer break,” Domenicali added.AdvertisementAdvertisementAdvertisement“We are monitoring the situation, because it would be an incredibly positive message for sport, and also politically, that we are moving in this direction, because if this is happening, it is something we can say is behind us.“I really hope that we can have all the conditions — safety first, of course, for all our people — [so] that we can go there.”
